2000 4cyl clutch replacement advice

2000 2wd, 4cyl, 200k miles, original everything. Decided to go ahead and replace the clutch based on mileage and occasional long distance trips. I attached some pictures for reference. Friction disk and pressure plate appear to be in ok shape. Flywheel as well. No grooving found. Couple of questions for you more experienced folks.

1) Was planning on buying oem parts from dealer. Dealer indicated he would needed to know if I had a luk or aisi clutch before ordering for me. Clutch is stamped luk. Could I install either style or does it make a difference? Is one better than the other?

2) Flywheel appears to be in great shape. Very shiny smooth surface. Is this what I should expect in a flywheel that doesn't need to be replaced or resurfaced?

Any other recommendations or advice? Was planning on replacing slave cylinder while having it pulled.

 

I would replace the clutch with the one that came in it. Also you should always resurface the flywheel. That shinny surface can cause slippage or clutch shudder when engaging a new clutch plate.
Also replace the throw-out bearing and check the clearance on the pilot bushing. Too much clearance can cause problems with the pilot shaft.
